Stopwatch: measure function execution time

I discussed this idea with @gusty once on the fssf Slack, but just wanted to know if this could be relevant for the scope of FSharpPlus.

Lss,

[<RequireQualifiedAccess>]
module Stopwatch

open System.Diagnostics


let measure f =
    let stopwatch = Stopwatch.StartNew()
    let r = f()
    stopwatch.Stop()
    (r, stopwatch.Elapsed)

It’s a simple helper, so not sure it is worthwhile to add it to the library

I was not aware of this class, but have made similar functions just using current time. I think it seems good.

The only other Stopwatch functionality amounts to being able to inspect seemingly constant IsHighResolution and Frequency (why are they instance fields then?) and to be able to continue timers.

I feel like these aren’t generally useful, and the measurefunction is what you’d normally want.

something like FSharpPlus.Scripting sounds good?
